What You Should Know About Smart Keys Smart keys – also referred to digital keys or information keys – allow drivers to access their vehicles without having to search for a keyhole. Certain vehicles come with them as standard features, whereas others provide them as an upgrade. The technology is also more modern than a traditional fob. Some systems allow you to start your vehicle without a traditional key fob or even a key. The best systems also include indicator lights for batteries that notify you when the battery is running low. Security Smart keys are more practical than traditional keys and also come with additional security and safety features. They utilize radio-frequency identification or RFID, to connect with your car's computer system. When the key is within the range of the antenna it is able to unlock the doors and start the car without having to make use of your phone or press a button. This could be a convenient feature. However, car thieves can penetrate this system and open your doors, or even start the engine. Certain manufacturers employ a technique known as “rolling codes” that stop this from happening. The code is projected by the key onto the starter and then checked by the computer in the car before it begins. This is to prevent thieves from creating multiple copies of keys. You can also ensure your vehicle is secure by not keeping the key and phone in the same pocket. If you place the two devices too close to each other can block the signals, which can stop them from communicating correctly. The KeySmart Pro has a built in Tile that will help you locate your phone. If you have the app installed on your iPhone and you put the Smart Key near it, pressing its activation button triggers the Tile to emit an elongated melody and flash an LED. This can be life-saving in the event that you lose your phone in a dark area or even if it is in silent mode. Convenience Smart keys can store and recall personal settings such as seat, mirror and steering wheel positions. Some, like BMW's Comfort Access, even allow you to start your car without having to press the ignition button. Modern smart keys communicate with car's antennas through radio waves. They transmit an encrypted message that is interpreted and acted upon by the computer. These signals can be modified to perform different tasks, such as opening and closing the trunk, or activating a child lock. The technology isn't completely foolproof, however. It's possible for tech-savvy thieves to detect the frequency of a smart key and then steal its unique identification number. Fortunately for us, the industry has been striving to increase the security of the system. Another feature that is useful is the ability to remotely lock and unlock your vehicle with a tap of the phone's screen. This lets you save time when loading your children or cargo. This can be particularly beneficial if you're parents of teenagers who are just learning how to drive. One of the best aspects of a smart key is its sleek slim design. It's easier to carry compared to other key organizers that can be large and take up more room than they need. KeySmart is also quiet and comfortable to carry. KeySmart is also quiet and easy to carry, removing that annoying jingle that can make you shiver. Battery Life Typically smart keys last for just half the time as regular fobs that have key blades (two to three years, versus four to six). The smart keys have to communicate with the car at a faster frequency and at a higher frequency in order to unlock and start the vehicle. Smart keys also consume more energy when placed near electronic devices that produce electromagnetic fields, such as phones, computers, and screens. The majority of smart keys come with batteries backup options. According to Open Road Auto Group most smart keys come with a blade that can be used as a traditional door key in the event that the battery of the smart key fob fails. They also have a slot that lets you insert an old-fashioned key to start the engine in the event that the smart key is dead or not working. A “power saving mode” is a second smart key backup. If you lose your smart key while driving, your car will continue to run even if it's not running. To accomplish this, you should place the smart key flat against the steering column of your vehicle, while pressing the ignition button once. If you've done this correctly, the system will alert the driver that it's not in the right place but still functioning. Cost Smart keys are not always affordable. Many owners of vehicles upgrade their keys to smart ones to enhance security and convenience. It can be costly to replace the lost smart key or reprogram your car. Smart keys look similar to regular key fobs, but they have a microchip that can be used to unlock, lock or start a vehicle without a physical one. The chip transmits a unique code to the vehicle's system, which detects and validates the code prior starting the engine. smart car key replacement cost has been around for a while however it's not perfect. This technique has been used by thieves to rob vehicles in several cases. There are ways to prevent this from happening. One method to avoid this is to use a smart key that has rolling security codes. The code changes each time the key is used. A key fob that has a display screen can also be very expensive. BMW's Display Key is an example of this kind of smart key. Its color LCD touchscreen can perform the standard functions of a key fob, such as locking, unlocking, and keyless start but it also send commands from an iPhone to the system of the vehicle. This makes it easier to use the vehicle and keep the track of its charging and the location of its battery. It can even command the vehicle to park itself. This is a great feature for people with limitations in mobility or have disabilities.
